Hi,

”One can access the non-PMBus registers(I2C register) via the MFR_REG_ACCESS(D0h) PMBus Command.” is written on page 36 of the data sheet.

1)We consider that the following protocol should be used when we read pmb_mfr_id(Common register).

Is that correct?

2) We consider that the following protocol should be used when we write “0” into loadline_range_sel(Common register).

Is it right?

Best regards,
MS

Hello,

We are using Powercode to configure PXE1110 and PXE1410 PWM controllers. 
How can I set parameters for poles/Zeroes, PID coefficients, Phase/Gain Margin in Feedback loop tab.

I am attaching a screenshot of the Feedback loop window.

Thanks

Hi all,

 1)TDA38740 has i2c_device_addr and pmb_device_addr.

i2c_device_addr can access Common registers and PMBus registers, and pmb_device_addr can access only PMBus registers.

Is that correct?

2)I consider that the format is as follows when we execute the OPERATION command with I2C and PMBus.

When we write with I2C, is the register address 12 bits?

Best regards,
MS

now I need design the request as follow:

input: 12V-dc

output current: 10~100A /constant current  

output volotage: 2~9V

can you introduct the design or the part?

Hi,

We use IR38363 in our design. 

Can someone let me know if the part mandatorily requires configuration through PMBUS/I2C Dongles? 

Will the component work without any I2C commands by default just by using external discrete?

Hello,

We are using Powercode to configure PXE1110 and PXE1410 PWM controllers. 

For Integrated Temperature sense type , what are the temperature offset, Internal and external Temperature threshold values that need to be set for fault handling.

I am attaching a screenshot of the temperature setting window.
